Abstract
A prefabricated door assembly for insertion in a door opening in a wall of predetermined thickness comprises side and head jambs of a width less than the wall thickness, and the frame is completed by extender casings each comprising a molding which is butt jointed to the outer surface of an extender piece that has its opposite edge butt jointed to its complementary jamb to complete a frame assembly of the proper width to fit the door opening with the molding pieces overlying the junction between the extender pieces and the wall. These features provide significant savings in the cost of materials and also in the space required for shipping the prefabricated base frame assemblies prior to addition of the extender casings thereto.
